Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If technicians manually connect pins in the data link connector, then pin connections can be established, but the challenging location of the engine control unit makes it difficult to access and connect proper pins
Solution Approach 1:
The patent introduces a jumper connector as an intermediary device that simplifies pin connections. The jumper connector has a housing that interfaces with the data link connector and contains pre-positioned jumpers that automatically align with specific pins, eliminating the need for technicians to manually locate and connect individual pins in the difficult-to-access engine control unit location.
2Reliability
If technicians manually locate and connect pins, then pin connections can be made, but errors occur in activating desired functionalities due to incorrect pin connections
Solution Approach 1:
The patent applies preliminary action by pre-configuring jumpers within the jumper connector housing before use. The jumpers are positioned in advance to connect specific pin pairs required for activating vehicle functionalities. This eliminates the need for technicians to manually determine and execute correct pin connections during the diagnostic process, thereby reducing errors while maintaining operational simplicity.
3Productivity
If a simple wire jumper is used to connect pins, then pin connections can be made, but the connection process is time-consuming and prone to human error
Solution Approach 1:
The patent merges multiple functions into a single integrated jumper connector device. The housing contains multiple pre-positioned jumpers that can simultaneously connect multiple pin pairs when the connector is inserted into the data link connector. This combination approach allows technicians to perform multiple pin connections in one action, significantly improving productivity while ensuring reliable and accurate functionality activation through pre-configured jumpers.

AI summary
A method and apparatus for jumping a pin connections in an electrical device are provided. The electrical device can be a vehicle having a data link connector that once mated with the apparatus, such a jumping connector that will jump at least two pin connections in the data link connector. The jumping connector can also have dip switches that be in the active or inactive state. In the active state, the dip switch will cause a connection to one of the pin connectors on the electrical device while the inactive state, the dip switch will not cause a connection to one of the pin connectors on the electrical device.
